Answer:
The speed of the boat in still water is 12 miles per hour, while the speed of the current is 9 miles per hour.
Step-by-step explanation:
We'll use x as the speed of the boat in still water in miles per hour.
We'll use y as the speed of the current in miles per hour.
When the boat is traveling downstream, the speed of the boat is helped by the speed of the current and the net speed is x + y.
When the boat is traveling upstream, the current opposes the movement of the boat, and the net speed is x - y.
Using a table where d = distance in miles, r = rate or speed in miles per hour, and t = time in hours can help figure out how to figure out this problem.
─────────────────
Downstream│210│(x + y)│10
Upstream│210│(x - y)│70
─────────────────
Recall that distance = rate x time or d = rt.
210 = (x + y)10 ➤ Equation from downstream information.
210 = (x - y)70 ➤ Equation from downstream information.
210 = 10x + 10y ➤ Distribute.
210 = 70x - 70y ➤ Distribute.
7 × 210 = 7 × 10x + 7 × 10y ➤ Multiply the 1st equation by 7.
1470 = 70x + 70y ➤ Add the 1st equation to the 2nd.
210 =70x - 70y ➤ Add the 1st equation to the 2nd.
1680 = 140x
─────────────────
1680/140 = 140x/140
x = 12
210 = (12 + y)10 ➤ Substitute x = 12 into one of the original equations to find y.
210 = 120 + 10y
-120 - 120
90 = 10y
90/10 = 10y/10
y = 9

Find the slope and y-intercept for this table.
Answers
Answer:
Slope is -5 and y-intercept is 90.
Step-by-step explanation:
Use the two values that you circles (4, 70) and (6, 60) .
slope (m) = the change in y-value/ (the change in the x-values).
m = (70 - 60)/(4 - 6) = 10/-2 = -5
The y-intercept is the value of "b" in the equation y = mx + b.
Using y = mx + b, substitute the value m and use point of your points (4, 70).
y = mx + b
70 = -5(4) + b Now solve for "b".
70 = -20 + b
+20 = +20
90 = b

Answer:
First one is False, second one is true.
Step-by-step explanation:
For the first one, the left side of the equation would equal -6/3, and the left side would be 3/-6. When simplified it would be: -2 = -1/2, which is incorrect.
For the second one, the left side and the right side are the same because either way you put it, they are still being multiplied, and the order doesn't matter. The end result will be -72 = -72, which is correct.

steve baked 5 1/2 batches of cookies in one and one half hours. Vondra baked 3 1/3 batches of cookies in 11/12 hour. Which baker made cookies at a greater rate of batches per hour?
Answers
Answer:
Step-by-step explanation:
Steve 11/2 batches / 3/2 hrs = 11/2(2/3) = 11/3 = 3 2/3 = 3 22/33 batches/hr
Vondra 10/3 batches / 11/12 hr = 10/3(12/11) = 120/33 = 3 21/33 batches/hr
Steve had a very slightly faster batch rate by only 1/33 batch/hr

hi guys can someone help me whit this question is for tommorow for my is so difficult . The exercise talks about math sets. It is: give three examples of sets A and B such that AU(union)B=B
Answers
Answer:
(i) A = {1}, B = {1, 2}, (ii) A = empty set, B = {1, 2, 3}, (iii) A = {a, b, c}, B = {a, b, c}, (iv) A = {7, 8, 9, 10}, B = {7, 8, 9, 10, 11, 12}
Step-by-step explanation:
The idea: A U B = the set of all elements (from a Universal set, like the set of all integers) that are in at least one of the sets A or B. So, for the equation A U B = B to be true, the set A must be a subset of the set B, because otherwise A U B would contain at least one element not in B, making the equation A U B = B false (set B would be a proper subset of A U B). So, if A = {1, 2, 3, 4} and B = {1, 2, 3}, then A U B = {1, 2, 3, 4}, and A U B = B would be false. However, if A = {1, 2, 3} and B = {1, 2, 3, 4}, then A U B = B would be true.

4:C(X) = 17x - 10, the first question wants you to find how much 5 ticket costs, so replace x with 5 so c(x)= 17(5)-10 which equals 75$
4a: 4a wants you to find how many tickets you can buy for 130$. So first replace the y or c(x) with 130 x, which gives 130=17x-10. Now we find x, first add 10 to both sides to cancel the -10, 140=17x, then divide 17 from both sides which gives 8.235, so we can buy 8 tickets.

F(x) =?. Vertex is (2,-4) the other given point is (1,-2)
Answers
We could substitute these values into the vertex form of the quadratic function,
f(x) = a(x - h)^2 + k
where:
(h,k) is the vertex
The axis of symmetry is the vertical line x = 2
The value of “a” determines whether the graph opens up or down, and makes the parent function wider or narrower.
The value of “h” determines how far left or right the parent function is translated.
The value of “k” determines how far up or down the parent function is translated.
Now that we’ve established these definitions, we can substitute the given values into the vertex form:
f(x) = a(x - 2)^2 - 4
In order to determine the value of “a”, we must substitute the values of the other given point, (1, -2) into the equation:
f(x) = a(x - 2)^2 - 4
-2 = a(1 - 2)^2 - 4
-2 = a(-1)^2 - 4
-2 = a - 4
Add 4 to both sides to solve for “a”
-2 + 4 = a - 4 + 4
2 = a
Now that we have the value of a = 2, we can establish our quadratic function in vertex form:
f(x) = 2(x - 2)^2 - 4
I’m also including a screenshot of the graph of the function we came up with.

Can Defects A company that makes soda pop cans finds that the
probability of producing a can without a puncture is 0.96, the probability that
a can does not have a smashed edge is 0.93, and the probability that a can
does not have a puncture and does not have a smashed edge is 0.893.
(a) Are the events "selecting a can without a puncture" and "selecting a can
without a smashed edge" mutually exclusive? Explain.
(b) If a quality inspector randomly selects a can, find the probability that the
can does not have a puncture or does not have a smashed edge
Answers
Using probability concepts, it is found that:
a) Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.
b) 0.997 = 99.7% probability that the can does not have a puncture or does not have a smashed edge.
Item a:
Two events, A and B, are mutually exclusive if:
[tex]P(A \cap B) = 0[/tex]
In this problem:
Event A: No puncture, thus, [tex]P(A) = 0.96[/tex].Event B: No smashed edges, thus [tex]P(B) = 0.93[/tex]The problem also states that the probability of neither is [tex]P(A \cap B) = 0.893[/tex].
Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.
Item b:
Using Venn probabilities, the "or" probability is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
With the given values:
[tex]P(A \cup B) = 0.96 + 0.93 - 0.893 = 0.997[/tex]
0.997 = 99.7% probability that the can does not have a puncture or does not have a smashed edge.
